A portable pet tether apparatus readily attaches onto a retractable pet leash. The portable pet tether allows a user to tether a pet anywhere. The portable pet tether consists of a corkscrew ground anchor that is rotatably connected to a leash receiver. The ground anchor is secured to the ground. The retractable pet leash can then be removably connected to the leash receiver through an attachment mechanism. The removably connected retractable pet leash may be detached from the leash receiver through the actuation of a release button.
